CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 14/522,716, filed Oct. 24, 2014, which claims the benefit of U.S. Provisional Patent Application No. 61/895,283, filed on Oct. 24, 2013. The entire disclosures of these applications are incorporated herein by reference.

TECHNOLOGICAL FIELD

Example embodiments of the present invention relate generally to vehicle maintenance and, more particularly, to a method, apparatus, and computer program product for improving the process of diagnosing and repairing vehicles.

BACKGROUND

Applicant has discovered problems with current vehicle diagnostic tools. Through applied effort, ingenuity, and innovation, many problems with existing diagnostic tools, methodologies, and systems are solved by the present invention, which is described in detail below.

BRIEF SUMMARY

A number of challenges are currently experienced by today's technicians. These challenges include limitations of current diagnostic hardware utilized within repair facilities, repair information lacking interactivity, and the challenge of maintaining many diagnostic tools, each having their own information sources. In short, technicians need to subscribe to multiple PC-based repair information sources, and must use multiple diagnostic tools each having their own information sources, resulting in subscription-fee fatigue.

For access to repair information through desktop PCs and laptops, sub-optimal behavior is common. Repair facilities often utilize one or two stand-alone units that technicians are allowed to share. The result is lost productivity due to technicians having to form a line to use the units and due to technicians having to traverse the shop floor to utilize this repair information source, and then having to walk back to the repair bay. In some instances technicians are required to print and then carry the required procedures to the bay, which does not leave room for error, or ease of access to additional follow-up information. Although laptops are slightly more convenient, technicians experience the same issue of having to share a limited number of laptops. In addition, technicians tend to have limited flat space to access laptops within a repair bay. A common result is that the technician must precariously balance the laptop while trying to navigate repair information.

For diagnostic tools, it has become increasingly common for repair facilities to support a multitude of devices, each having its own associated fees and software (including concomitant software/firmware updates). These systems vary from entry-level hand-held scan devices, to OE level diagnostic scanners. Each such system, however, is disconnected from the others, and there is no centralized data store that conveniently collates data from all sources. Moreover, most such systems are disconnected from any web-based information source entirely, and consequently introduce inconvenience into the process of gathering relevant information.

Similarly, prior art systems typically require separate tools for the different manufacturers. Accordingly, a need exists for a tool that provides access to information from multiple OEM manufacturers, rather than only some subset thereof.

For web-based repair information access, current systems are designed for technicians to manually enter vehicle year, make, model, and engine (YMME) information, and then follow repair procedures, with no interactivity. In other words, current web-based information retrieval systems follow a simplistic paradigm that is prone to data entry errors.

All of the above problems contribute to repair inefficiency in repair facilities and produce negative impacts on profit margin, repair speed, and cost to consumers.

To address some of these weaknesses of current shop platforms, a method, apparatus, and computer program product are provided in accordance with example embodiments of the present invention to improve the diagnosis and repair of vehicles. Embodiments of the present invention offer the convenience, reliability, durability, and low operational cost of current tablet application technology. Embodiments of the present invention further offer the ability to transport repair information anywhere as needed (avoiding the inconvenience of immobile stand-alone units), and offer expanded functionality not otherwise available through devices (e.g., laptops) that are not easily carried or handled in a repair bay. Moreover, embodiments of the present invention leverage tablet technology by providing expanded functionality not available through traditional web browsers, and providing a touchscreen-enabled user interface (UI) having repair information types laid out within an easy-to-use grid format.

In addition, using embodiments of the present invention, technicians are able to connect to vehicles through the on-board diagnostics (OBD) port of a vehicle, automatically read vehicle identification number (VIN) information, and retrieve relevant repair information and identify diagnostic trouble codes (DTCs, or “codes”) as part of an initial diagnostic process. This functionality bridges the gap between repair information and vehicle connectivity. Moreover, using OBD parameter IDs (i.e., PIDs, such as those defined in the SAE J1979 standard, which is incorporated herein by reference in its entirety) to request data from a vehicle, embodiments of the present invention are able to retrieve corresponding DTCs (such as p-codes, a particular type of code), correlate these codes to specific repair articles, and store either the codes, the repair articles, or both, within a user's account in conjunction with the affected vehicle's VIN.

Embodiments of the present invention provide repair information served through the convenience, reliability, durability, and low operational cost of tablet application technology. In this regard, the present invention may enable technicians to transport repair information anywhere as needed, with expanded functionality not available through traditional systems, thus mitigating the need to wait in lines to access terminals. Accordingly, embodiments of the present invention may overcome inefficiencies of traditional vehicle maintenance systems, and provide a competitive advantage to maintenance facilities.

The above summary is provided merely for purposes of summarizing some example embodiments to provide a basic understanding of some aspects of the invention. The above-described embodiments are merely examples and should not be construed to narrow the scope or spirit of the invention in any way. It will be appreciated that the scope of the present invention encompasses many potential embodiments including those here summarized, some of which will be further described below.

System Architecture

FIG. 1 discloses an example computing system 100 within which embodiments of the present invention may operate. In this regard, the method, apparatus, and computer program product of an example embodiment may be embodied by a computing device 102, such as a tablet computer (e.g., an Apple iPad™, Samsung Galaxy Tab™, Google Nexus™, Microsoft Surface™, or the like), configured to communicate with one or more vehicles via an OBD port 110 (e.g., a port in accordance with OBD-II, EOBD, JOBD, ADR 79/01, ADR 79/02, J2534, or any other standard by which a device may communicate with a vehicle's on-board computer), and further configured to communicate with a server 104 via a network 112, such as a local area network (LAN), or a wide area network (e.g., the Internet). In some embodiments, the computing device may be embodied by any of a variety of other mobile terminals, such as a portable digital assistant (PDA), mobile telephone, smartphone, laptop computer, or any combination of the aforementioned devices.

Server 104 may comprise a web server connected to the Internet, and may comprise several constituent elements. For instance, server 104 may include one or more databases storing partnered diagnostic data, VIN/YMME data, repair data (such as repair instructions, information regarding DTCs, p-codes, or the like), and historical data regarding one or more OEM manufacturers, one or more users, or one or more vehicles. By storing a comprehensive set of information, these databases mitigate the traditional problem in which multiple tools are required to gather information for different manufacturers, and enables repair facilities to replace multiple tools with a single tool. Similarly, by reducing reliance on a multitude of tools, embodiments of the present invention may mitigate the problem of subscriber-fee fatigue.

The system shown in FIG. 1 may further include an adaptor 106 (e.g., a PLX Kiwi™, Kiwi™ 2, OBDLink MX, OBDLink LX, or other similar device) via which the computing device 102 connects to OBD port 110. In this regard, adaptor 106 may connect directly to OBD port 110, and may be configured to connect to computing device 102 via Bluetooth™, Wi-Fi™, universal serial bus (USB), or any other wired/wireless connection.

The computing device 102 may be embodied by a computing system, such as apparatus 200 shown in FIG. 2. As illustrated in FIG. 2, the apparatus 200 includes a processor 202, memory 204, user interface 206, communications module 208, and may in some embodiments include vehicle interface 210. In some embodiments, the processor 202 (and/or co-processor or any other processing circuitry assisting or otherwise associated with the processor) may be in communication with the memory 204 via a bus for passing information among components of the apparatus. The memory 204 may be non-transitory and may include, for example, one or more volatile and/or non-volatile memories. In other words, for example, the memory may be an electronic storage device (e.g., a computer readable storage medium). The memory may be configured to store information, data, content, applications, instructions, or the like, for enabling the apparatus to carry out various functions in accordance with example embodiments of the present invention.

The processor 202 may be embodied in a number of different ways and may, for example include one or more processing devices configured to perform independently. Additionally or alternatively, the processor may include one or more processors configured in tandem via a bus to enable independent execution of instructions, pipelining, and/or multithreading.

In an example embodiment, the processor 202 may be configured to execute instructions stored in the memory 204 or otherwise accessible to the processor. Alternatively or additionally, the processor may be configured to execute hard-coded functionality. As such, whether configured by hardware or software methods, or by a combination thereof, the processor may represent an entity (e.g., physically embodied in circuitry) capable of performing operations according to an embodiment of the present invention while configured accordingly. Alternatively, as another example, when the processor is embodied as an executor of software instructions, the instructions may specifically configure the apparatus 200 to cause the processor to execute the algorithms and/or operations described herein.

In some embodiments, the apparatus 200 may include a user interface 206 that may, in turn, be in communication with processor 202 to provide output to the user and to receive an indication of a user input. The user interface 206 may include a display and may comprise a web user interface, a mobile application, a client device, a kiosk, or the like. In some embodiments, the user interface 206 may also include a keyboard, a mouse, a joystick, a touchscreen, touch areas, soft keys, a microphone, a speaker, a camera, or other input/output mechanisms. The processor and/or user interface circuitry comprising the processor may be configured to control one or more functions of one or more user interface elements through computer program instructions (e.g., software and/or firmware) stored on a memory accessible to the processor (e.g., memory 204, and/or the like).

Meanwhile, the communication module 208 may be any device or circuitry embodied in either hardware or a combination of hardware and software that is configured to receive and/or transmit data to or from a server 104 in communication with the apparatus 200. In this regard, the communication module 208 may include, for example, an antenna (or multiple antennas) and supporting hardware and/or software for enabling communications with a wireless communication network. Additionally or alternatively, the communication module 208 may include the circuitry for interacting with the antenna(s) to cause transmission of signals via the antenna(s) or to handle receipt of signals received via the antenna(s). In some environments, the communication module 208 may additionally or alternatively support wired communication. As such, for example, the communication module 208 may include a modem and/or other hardware/software for supporting communication via cable, digital subscriber line (DSL), universal serial bus (USB), or other mechanisms. The communication module 208 may additionally send and retrieve data from peripheral devices such as a printer or point-of-sale terminal (not shown in FIG. 2), and in some embodiments, the communication module 208 may facilitate the transmission of received information via the Internet (e.g., via email, text messaging, social media platforms, or the like).

In some embodiments, the apparatus 200 may further include vehicle interface 210, which is configured to enable communication between the apparatus 200 and a vehicle's on-board circuitry via the vehicle's OBD port 110. The vehicle interface 210 may in some embodiments comprise adaptor 106, as described above. Alternatively, the vehicle interface 210 may comprise a component configured to communicate with adaptor 106 via a wired/wireless connection, as described above. Accordingly, vehicle interface 210 enables communication between the apparatus 200 and a vehicle, in close proximity or remotely.

Server 104 may also be embodied by a computing system such as apparatus 200 illustrated in FIG. 2. In this regard, server 104 may include a processor 202, memory 204, and communication module 208, and may optionally include a user interface 206. Server 104 may process, host, and publish large amounts of content relevant to vehicle DTCs, p-codes, problem diagnosis, and repair instructions, wherein such information is accessible by a technician via computing device 102.

Server 104 need not include vehicle interface 210, and in some embodiments may not communicate directly with a vehicle. In such embodiments, server 104 may function as a database that can be queried via communication module 208 (e.g., by computing device 102) and may provide information relevant to particular queries, such as repair instructions relevant to specific DTCs, or related to particular users or vehicles (e.g., by uploading related DTC information to a computing device 102 upon login by a particular user or connection of the computing device 102 to a particular vehicle). Alternatively, in some embodiments, server 104 may itself include a vehicle interface 210, and may accordingly be configured to retrieve data from a vehicle irrespective of the operation of a computing device 102. Server 104 may accordingly retrieve and store DTCs for subsequent reference or download by computing device 102 or merely for storage as historical data. Similarly, server 104 may locate information relevant to retrieved DTCs for efficient retrieval upon request by computing device 102. In yet another alternative, in some embodiments computing device 102 and server 104 may comprise a single system or device including vehicle interface 210. In some such embodiments, the combined system may comprise a sufficiently powerful device usable by a technician.

Server 104 may further perform additional tasks related to vehicle diagnostics and repair. For instance, by collecting historical data (e.g., user information, vehicle information, and DTCs associated with particular users and/or vehicles over time), server 104 may, in some embodiments, mine the collected data to develop diagnostic predictions based on the historical data and statistically significant correlations between various elements of the historical data. For instance, server 104 may determine likely problems for a first vehicle based on historical DTC information of similarly situated vehicles, and in this regard may identify problems endemic to particular vehicle years, makes, models, engines, or even manufacturers. Server 104 may determine estimates of when, during a vehicle's lifetime, DTCs are likely to occur, and may identify combinations of DTCs that frequently occur together, and may even, in some embodiments, identify statistically significant correlations between DTC information and particular users or regions, or even seasonal changes in DTC occurrences. In some embodiments, the server 104 may transmit such information to computing device 102 in response to receiving, from the computing device 102, user identifying information, vehicle information (e.g., VIN or YMME), or any sequence of information suggesting the relevance of such statistical data.

Application Architecture and User Interface

As noted above, a method, apparatus, and computer program product are provided in accordance with example embodiments of the present invention to improve the diagnosis and repair of vehicles. Embodiments of the present invention offer the convenience, reliability, durability, and low operational cost of current tablet application technology. Embodiments of the present invention further offer the ability to transport repair information anywhere as needed (thus avoiding the inconvenience of immobile stand-alone units), and offer expanded functionality not otherwise available through devices (e.g., laptops) that are not easily carried or handled in a repair bay. By providing the technician with a tablet device, embodiments of the present invention may eliminate the problem of having to precariously balance a laptop on the small or uneven surfaces within a repair facility. Moreover, embodiments of the present invention leverage tablet technology by providing expanded functionality not available through traditional web browsers, and providing a touchscreen-enabled user interface (UI) having repair information types laid out within an easy-to-use grid format.

To streamline the process of diagnosing and repairing vehicles, embodiments of the present invention execute software stored on computing device 102. This software may enable technicians to quickly and accurately identify vehicles, locate DTCs corresponding to potential vehicle faults, and retrieve information relevant to diagnosing problems and repairing them. In this regard, the application software may include three types of operation: (1) reading/saving/clearing standard DTCs (including linking to associated articles from server 104) via interfaces including the SAE J2534-2 standard, emissions monitoring checks, displaying data from a number of on-board modules in a variety of formats (list, graph, etc.), and providing access to non-powertrain protocols (e.g., ABS, SRS, BCM); (2) reading/saving/clearing DTCs related to powertrain (ECM, PCM, TCM), including chassis and body systems; and (3) bi-directional testing, adapting, coding, and programming of vehicle on-board circuitry (e.g., using the SAE J2534-2 standard).

Initially, computing device 102 may establish a connection, via adaptor 106, with OBD port 110 of a vehicle. This may occur in at least three distinct ways. As shown in FIG. 3A, in some embodiments establishing a connection to the vehicle may be as simple as plugging a cable connected to adaptor 106 into the OBD port 110 of the vehicle, after which this physical connection triggers identification of the adaptor 106 by computing device 102. In other embodiments, the computing device 102 may be connected wirelessly to the adaptor. In one such embodiment, a Wi-Fi connection may be established as shown in FIGS. 3B through 3D. In this regard, to connect to adaptor 106 via a Wi-Fi connection, the technician may select Wi-Fi settings in computing device 102, as shown in FIG. 3B. In FIG. 3C, the technician may select the Wi-Fi connection associated with adaptor 106. Finally, in FIG. 3D, the technician may select a “static” IP address setting and enter the appropriate IP address and subnet mask associated with adaptor 106.

In another such embodiment, the computing device 102 may connect to adaptor 106 (e.g., an OBDLink MX, shown in FIG. 3E) via other wireless means (Bluetooth™, or the like), in which case one or more adaptor 106 may be automatically detected by the computing device 102, and may appear as a selectable icon, as shown in FIG. 3F. In one embodiment, from the example user interface shown in FIG. 3F, if the user selects the “OBDII” icon 302, the computing device 102 initiates a scan for compatible adaptors 106. The computing device 102 can present a user interface that displays one or more icons including descriptive information regarding the compatible adaptors. FIG. 3F shows the user interface after pairing with a particular adaptor. Upon selection of the “gear” icon to the right of the circled adaptor, the user may enter a new name for the adaptor, in order to distinguish it from other adaptors that may also be detectable via wireless means. Selection of the “gear” icon provides a user interface (shown in FIG. 3G) for entering a new adaptor name, which in this example would replace the text “OBDLink MX” after completion. Notably, because a particular repair facility may use multiple adaptors 106 (e.g., an adaptor for each repair bay in the facility), embodiments described herein present a practical and efficient mechanism for setting recognizable names for each adaptor 106, to make it easier to distinguish these various adaptors 106.

For instance, the descriptive information corresponding to each adaptor may identify the physical locations of each of the adaptors. By selecting the appropriate icon representing an adaptor, a user can cause the computing device to establish a connection with the adaptor based on this physical location. See, for example, the user interface shown in FIG. 3H, which illustrates adaptors that are physically located in Repair Bay 01 and Repair Bay 02, and which have corresponding adaptor names identifying their physical locations. In this example, the computing device 102 can identify an adaptor to communicate with and can establish a connection between the apparatus and an adaptor based on the physical locations of the adaptors. In some embodiments, the adaptors 106 may transmit physical location information in response to an initial scan for compatible adaptors 106. In such embodiments, the descriptive information identifying the physical location of the adaptors may be generated based in part on the physical location information transmitted by the adaptors 106.

Turning now to FIG. 4A, a main screen interface is illustrated that may be displayed to a technician by user interface 206. The icons in box 402 are shortcuts to specific types of information from server 104. In some embodiments, these shortcuts describe frequently queried DTCs, frequently viewed maintenance information, and information regarding technical service bulletins and product recalls. The icons in box 404 comprise a refresh icon, which refreshes the current display, and a back icon, that returns the technician to the previous window. In some embodiments, the icons contained in box 402 (illustrated in the example shown in FIG. 4A in the bottom middle of the screen) may be located elsewhere, so long as they are accessible by user interaction with the user interface 206. FIGS. 4B through 4D highlight the three columns of information presented by the application. The left column, highlighted in FIG. 4B, illustrates vehicle information about a currently connected vehicle (identified in the manner discussed below in conjunction with FIGS. 5A through 5C), and a list of previously selected and/or diagnosed vehicles. This list may be independently scrollable, depending on the number of vehicles that have previously been loaded by the interface. The middle column, highlighted in FIG. 4C, contains a set of icons selectable to receive more granular repair information regarding the various systems of the selected vehicle. This list may independently scroll to reveal additional repair information that may not fit onto the display. Finally, the right column, as shown in FIG. 4D, contains vehicle diagnostic trouble codes that have been stored by the computing device 102 and that are retrieved when connected to a vehicle's computer. This column may also independently scroll based on the number of DTCs stored and/or downloaded. As shown in FIG. 4E, in some embodiments described herein, user interface 206 may include the vehicle information column and the repair information column, but need not include a column of diagnostic trouble codes, which may instead be accessible from an alternative location in the user interface 206. For instance, FIG. 4F illustrates a drop-down menu enabling a user to view separate vehicle diagnostics displays, which are described below in association with FIGS. 4G through 4J.

FIG. 4G illustrates an example of a vehicle diagnostics display that illustrates a similar set of information as illustrated in the right column highlighted in FIG. 4D. FIG. 4H illustrates an example vehicle diagnostics display illustrating sensor value information. Selection of a preferred PID from the drop-down menu within this display illustrates the corresponding sensor value information.

FIG. 4I presents an example emissions readiness display, which illustrates various systems and subsystems that may be monitored. In this display, “Continuous” monitors are running at all times, while “Drive to Activate” monitors must complete full drive cycles or meet specific operating conditions to activate. As can be seen in the example shown in FIG. 4I, the “EGR” is not active. The “MIL” icon displays the status of the vehicle's malfunction indicator light. As with the similar icon in FIGS. 4G through 4J, the “Clear Active Codes” icon clears all active codes that are currently being held by the vehicle's ECU, which in this case will also reset all emissions readiness monitors. Finally, the “Disconnect” icon terminates the connection from the tablet to the vehicle.

Finally, FIG. 4J illustrates an example vehicle diagnostics freeze frame display. This display illustrates the PID values associated with a specific DTC at the moment the DTC occurred, to provide a better idea of what conditions the vehicle was under when the DTC was set. The freeze frame display illustrates the DTC number and description, as well as all available freeze frame data. If multiple DTCs exist, freeze frame information may be shown only for the first DTC. Selection of the “View DTC Article” icon opens a corresponding troubleshooting article for the specified DTC. Selection of the “Refresh” icon refreshes the page with the most current freeze frame data. Selection of the “Freeze Frame History” icon displays previously captured DTC freeze frame data.

Turning now to FIGS. 5A through 5C, the application may automatically gather VIN and YMME information, and capture DTCs from the vehicle. In this regard, the computing device 102 is configured to identify the specific vehicle under examination, thereby avoiding the need to enter such identifying information by hand, which in traditional systems takes time and introduces opportunities for error. Accordingly, embodiments of the present invention are able to mitigate data entry errors by reducing the need for human involvement in VIN and/or YMME identification. To gather the VIN and YMME information of the vehicle, the technician selects the “connect” icon located centrally in FIG. 4E (and located, alternatively, in the top right corner of FIG. 4A), a zoomed-in illustration of which is shown in FIG. 5A. Upon selection of this icon, the computing device 102 retrieves the VIN and YMME information for the vehicle and displays it to the user in the left column (shown in FIGS. 4B and 4E) displayed on the user interface 206. In this regard, each computing device 102 (or technician or repair facility) may have a user account and associated user identifier, which may be maintained by server 104. Upon connection to the vehicle, all information collected regarding the vehicle may be uploaded to server 104 and stored in a historical database for future reference by the computing device 102, the technician (or another technician at the repair facility). As a result, embodiments of the present invention enable the creation and maintenance of a history of repair information regarding individual vehicles, which in turn may nurture loyalty by the technician or repair facility. While this information may be stored by server 104, this user account information may additionally or alternatively be stored locally by the computing device 102.

A successful connection is shown in FIG. 5B, after codes may be retrieved from the vehicle and stored by the computing device 102 for display via user interface 206, and may further be transmitted to the server 104 for storage in association with the user's account and the YMME and/or VIN information previously retrieved. Subsequently, any generated codes can be previewed (in the right column in FIG. 4D) on the main screen displayed by user interface 206, or in alternative embodiments, in the DTC pane shown in FIG. 4G. In this regard, to view and clear active codes captured from the connected vehicle, the technician may select “Vehicle DTC history,” a selectable icon located, in some embodiments, in the vehicle diagnostics display shown in FIG. 4G, a zoomed-in illustration of which is shown in FIG. 5C.

In some embodiments, the technician may be able to select a “Vehicle DTCs” tab or “Vehicle DTC History” tab, as shown in FIG. 5D. Upon selection of the “Vehicle DTCs” tab, the technician can either click a listed code to view DTC repair information, or clear codes by selecting a “Clear Codes” button. Clicking a listed code to view DTC repair information initiates a query from computing device 102 to server 104 keyed on the specific code selected. Because each code is associated with unique repair and/or diagnostic data in server 104, this query returns the relevant information for display by user interface 206 of the computing device 102. Upon selection of the “Vehicle DTC History” tab, computing device 102 can retrieve historical codes for the vehicle from the technician's user account and/or repair facility's account at server 104. This historical DTC information is then displayed to the technician via user interface 206.

To view specific PID information while connected to the vehicle (which in some embodiments comprises real-time sensor data retrieved from the vehicle via vehicle interface 210), the technician may either select the “Sensors” button shown in FIG. 5C, or the ‘Sensors” icon shown in FIG. 5E. Subsequently, to navigate through supported PID's, the technician may selectnavigate to the “Sensors” display within the top right of the resulting user display, as shown in FIG. 4H, another example embodiment of which is shown in FIG. 5F. Each supported PID may then be used to query the vehicle for relevant DTCs.

In some embodiments, the technician may change the vehicle under evaluation. In one such embodiment described above, by selecting the “connect” button, the VIN and YMME information of a currently-connected vehicle may be retrieved, via a vehicle interface 210, from the adaptor 106, and that vehicle's data may be automatically selected. Alternatively, by selecting the “Change Vehicle” button within the “Current Vehicle” frame in the left column on the main screen (highlighted in FIG. 4B) or using the “Select New” button shown FIG. 4E, or by selecting the car icon shown in FIG. 5G, the technician may manually select another vehicle. When the vehicle selection screen 5H appears, the technician may enter the year, make, and model within drop-down menus, and then select an engine type, or alternatively may manually enter vehicle identifying information in the text field. In some embodiments, the technician may also enter search terms in the text field, in response to which relevant previous vehicles may be presented (for instance, if a technician enters the search term “03 MDX,” the list may be populated with a 2003 Acura MDX for selection). To quickly select previously viewed vehicles, the technician may also select one of the vehicles listed in the “Previous Vehicles” frame located in the left column on main screen (highlighted in FIG. 4B or shown on the left portion of the display shown in FIG. 4E).

Moreover, the technician may access specific repair information from the main screen by either selecting a specific system or the vehicle button within the center column (highlighted in FIG. 4C), a zoomed-in illustration of which is shown in FIG. 5I. As noted above, the computing device 102 retrieves this specific repair information for display by sending a corresponding query to server 104. By selecting the “Vehicle” icon, the technician may view the “Repair Information Home” screen shown in FIG. 5K. To navigate to specific components of the vehicle, the technician may select the “System” folder, “Sub-System” folder, and then continue to the associated component, shown in FIG. 5J.
